Application filed April 7, 1919. Serial No. 288,147.

To all whom it may concern Be it known that I, BYRON K. Ln Gnome, acitizen of the United States of America, a

resident oi- Efl'ingham, in the county of Effingham, State of Illinois,haveinvented certain new and useful Improvements in.

Apparatus for Making Stereotypes, of which the following is a fu 1,clear, and exact de-' scription, reference being had to the accompanyingdrawings, forming a part of this specification.

My invention relatesto a self-contained stereotype casting apparatushaving therein all of the essentials of a stereotype molding operationand so constructed as to provide for the quick and easy transfer ofmolten metal from a melting pot to the stereotype casting box, therebymaking it possible to produce electrotypes at the maximum of speed.Furthermore, the apparatus is so constructed as to provide for instantassemblage and separation of the elements of the apparatus, sothat theparts maybe asembled and disassembled without the use of connectinappliances requiring time for their manipulation.

Figure I is a top pla'n view of my stereotype making apparatus, portionsof the melting pot and casting box being shown broken out and insection.

. Fig. II is a side elevation of the apparatus which preferably includesinclined rear members 1 and front members 2, connected by upwardlyextending joined arms 3 prov1ded with a keeper 4. 5 is a burnersupported by the stand A, said burner bein of any suitable constructionfor supplying eat to melt the metal used in making stereotypes.

6 designates a tilt table pivoted intermediate of its ends to the upperportion of the stand A by trunnions 7. Said table is adapted at one timeto occupy a horizontal position, in which its front end rests upon aledge 3 at the upper end of the arm 3 of the stand A, as seen in Fig.II, and at another time occupies a tilted or inclined position, as shownin Fig. III. When the tilt .the separable sections of which are heldasser'nbled in any ordinary manner. The casting box, which is intendedto hold a matrix as usual, is provided at one of its ends with amouthpiece 10 through which molten metal is poured to enter the box,said mouthpiece having formed thereon or secured thereto side lugs 11 ofutility to be hereinafter mentioned. l i

12 designates a melting pot of e g shape, as shown, or of any othersuitable shape. This melting pot occupies an opening in the forwardportion of the tilt table 6 and is provided with a top opening throughwhich metal to be melted may be introduced and whichis normally closedby a door 13. At the rear end of the melting pot is a mouthpiece 14 withwhich the mouth-piece 10 on the casting box 6 registers when the castingbox and melting pot are in position upon the tilt table 6.

At each side of the melting pot 12 is a side lug 15 adapted to seatwithin and be held by an L-shaped arm. carried by the tilt table 6, thelugs 15 being located in front of the legs of said L-shaped arms, andthe wings of said arms extending forwardly from said lugs, therebypreventing either rearward or upward movement of the melting pot whenthe lugs 15 are in engagement with the arms 16.

The melting pot 12 is also provided with rearwardly extending hook arms1 having vertical fingers 19 spaced from each other a distance greaterthan the width'of the mouthpiece 10 of the melting pot 9, and adapted tobe engaged by the side lugs 11 carried b said mouthpiece. By engagingthe side ugs 11 on the mouthpiece of the casting box with the fingers ofthe hook arms 18, the mouthpiece of the casting box is held inengagement with the mouthpiece .of the melting pot.12, and to make suchengagement firm the forward faces of the hook arm fingers 19 areinclined, as seen at 19, and the rear faces of the lugs llare alsoinclined, thereby providing a wedging action between said lugs andfingers which results in the adjustment of the smooth end ing downwardlyfrom the rearward projecfaces of the mouthpieces and 14 into closecontact.

The melting pot 12, in addition to being i detachably connected to thetilt table 6'by the engagement of the 1ugs15 with the L-- arms 16 on thetable, is also placed mengagement with said table by a lug 17 extendtionof the pot which carries the hookarms 18. The melting pot is thereforeengaged with the tilt table at three points, two of which preventrearward movement of the pot on the'table and. the other of which holdsthe pot from lateral movement.

In the use of my apparatus,the melting pot is readily slipped into placeon the tilt, table 6 by disposing it in the opening 1n the forwardportion of the table and moving it 'rearwardly, so that the side lugs 15w1ll become engaged with the L-arms 16 and the lug 17 will drop into theopening provided therefor in the table. The melting pot having beensecuredin place, a casting box having the described mouthpiece is sopresented to the melting pot as tocause the side lugs of its mouthpieceto ride downwardly along the inclined forward 'faces of the hook armfingers 19 until the two mouthpieces 10 and 14 arebrought intoregistering relation and held firmly assembled to avold leakage of metalthrough the joint between the mouthpieces. The operations just describedare performed while the tilt table is in the horizontal position shownin Figs. I and 11. Assuming now that molten metal, heated by V the useofthe burnerv 5, is present in the melting pot, the next act. of theoperator is to release the.latch 8 and tilt the table 6 from thehorizontal position to the inclined position shown in Fig. III. By sotilting the table the melting pot and the casting box supported thereonare placed in inclined position, the molten metal passing from the potto the box through the mouth pieces 14 and 10, with resultant castingoperation.

. The tilttable'is then returned to a horizontal position prior to theseparation of the M casting box from the melting pot. To per mit theready separation of the casting box from the melting pot'the lowerportions of the lugs 11, carried by the mouthpiece of the casting box,are rounded or cut away, as seen at 1-1, so that the rear edges of theseportions of the lugs are separated from the opposing portions of thehook arm fingers l9 engaged by the remaining portions of the lugs. Thesecut away portions'of the lugs 11 enable the operator to tilt the castingbox casting boxes may be employed in the use of my apparatus, it beingessential only'that the mouth piece of the box, irrespective of the sizeof the box, be of a size and shape to fit the mouth piece of the meltingpot.

' I claim:

An apparatus of the character described, comprising a fitiltablesupport, a melting pot arranged on said support, said melting pot havinga mouthpiece, and acasting box having a mouthpiece, one of said :partshaving hook arms and the other hair ing elements for engagement withsaid hook arms whereby the parts are connected to each other toholdsaidmouthpieces-in mating relation. 2. apparatus of the character:described, comprising a tiltable support, a
